Event description

Description

The Joseph Priestley Society welcomes David Liu, scientist at specialty chemicals and advanced materials company Arkema, and Kevin Turner, professor and chair of mechanical engineering and applied mechanics at the University of Pennsylvania.



The 3-D printing process builds a three-dimensional object from a computer-aided design model by adding material, such as liquid resin or powder grains being fused together, layer by layer. This process is also known as additive manufacturing. In the early 1990s, 3-D printing techniques were considered suitable only for the production of functional or aesthetic prototypes. Fast-forward 30 years, and the speed, precision, repeatability, and material range have increased to the point that 3-D printing processes are now used in commercial industrial production. One of the key advantages of 3-D printing is the ability to produce very complex shapes or geometries directly without need for a mold. Thus the technology also lends itself to mass customization, where items, such as running shoes, can be customized to an individual’s needs.

Turner will discuss advances in the basic understanding of mechanical design of materials and components made via additive manufacturing. Liu will detail some of the state-of-the-art developments in additive manufacturing for the industrial scale; he has spent the last few years developing polymeric materials specifically for this application.

About the Speakers

David S. Liu is a research scientist at Arkema, a specialty chemicals and advanced materials company. He joined the company in 2014 and has been exploring the use of Arkema’s material in 3-D printing. During the last five years he has applied for multiple patents, with one granted, on improved materials and methods of printing for ultraviolet curing and material extrusion additive manufacturing. Arkema has commercialized many new thermoplastic materials for material extrusion additive manufacturing based on his research.

Liu received a BS in chemical engineering from Caltech in 2007. He attended graduate school at MIT, where he received an MS in chemical engineering practice in 2010 and a PhD in chemical engineering in 2014. At MIT he worked under the guidance of Paula Hammond, researching ways to improve proton conduction in composite membranes for fuel cells.

Kevin T. Turner is a professor and the chair of mechanical engineering and applied mechanics at the University of Pennsylvania. He holds a secondary appointment in materials science and engineering. Before joining the University of Pennsylvania in 2011, he was on the faculty of the University of Wisconsin, Madison.

Turner’s research is at the nexus of mechanics, manufacturing, and materials, with a particular emphasis on problems involving small-scale systems and interfaces. He has extensive experience in the mechanics of adhesion and fracture, micro- and nano-systems, and advanced manufacturing. Ongoing research efforts include structured materials with controllable adhesion and fracture behavior, additive manufacturing of cellulose nanomaterials, soft robotic grasping, nanocomposites, and manufacturing of flexible hybrid electronics and sensors.

He received a BS in mechanical engineering from Johns Hopkins University and an SM and a PhD in mechanical engineering from MIT.
